Ting's answer: he's ready for something new. We fear that a vacancy in his office would allow Mayor Ed Lee to appoint someone with less interest in tax equity (prior to Ting, the city suffered mightily under a string of political appointees in the Assessor's Office), but we're pleased to endorse him for the District 19 slot.

Ting has gone beyond the traditional bureaucratic, make-no-waves approach of some of his predecessors. He's aggressively sought to collect property taxes from big institutions that are trying to escape paying (the Catholic Church, for example) and has taken a lead role in fighting foreclosures. He commissioned, on his own initiative, a report showing that a large percentage of the foreclosures in San Francisco involved some degree of fraud or improper paperwork, and while the district attorney is so far sitting on his hands, other city officials are moving to address the issue.

His big issue is tax reform, and he's been one the very few assessors in the state to talk openly about the need to replace Prop. 13 with a split-role system that prevents the owners of commercial property from paying an ever-declining share of the tax burden. He wants to change the way the Legislature interprets Prop. 13 to close some of the egregious loopholes. It's one of the most important issues facing the state, and Ting will arrive in Sacramento already an expert.

Ting's only (mildly) serious opponent is Michael Breyer, son of Supreme Court Justice Breyer and a newcomer to local politics. Breyer's only visible support is from the Building Owners and Managers Association, which dislikes Ting's position on Prop. 13. Vote for Ting.

DEMOCRATIC COUNTY CENTRAL COMMITTEE

You can say a lot of things about Aaron Peskin, the former supervisor and retiring chair of the city's Democratic Party, but the guy was an organizer. Four years ago, he put together a slate of candidates that wrenched control of the local party from the folks who call themselves "moderates" but who, on critical economic issues, are really better defined as conservative. Since then, the County Central Committee, which sets policy for the local party, has given its powerful endorsement mostly to progressive candidates and has taken progressive stands on almost all the ballot issues.

But the conservatives are fighting back — and with Peskin not seeking another term and a strong slate put together by the mayor's allies seeking revenge, it's entirely possible that the left will lose the party this year.

But there's hope — in part because, as his parting gift, Peskin helped change state law to make the committee better reflect the Democratic voting population of the city. This year, 14 candidates will be elected from the East side of town, and 10 from the West.

We've chosen to endorse a full slate in each Assembly district. Although there are some candidates on the slate who aren't as reliable as we might like, 24 will be elected, and we're picking the 24 best.
